The Russo-Turkish Treaty' for the Dismemberment of
Persia, A.D. 1724.—Negotiations between Turkey and
Russia were resumed and culminated in an agreement for
the partition of the most valuable provinces of Persia.

which was justly regarded as the strongest fortress in the
country. Operations were pushed on with the utmost
determination, and in spite of the loss of twenty thousand
men in four assaults and by disease Erivan was taken in
A.H. r 137 (i724) after a three months' siege ; the garrison
marched out with the honours of war.
The victorious army was now directed against Tabriz.
A Persian force ten thousand strong was defeated outside
